315745 OMC PLATE IMPELLER

The OMC Johnson/Evinrude 315745 is an impeller housing plate, a critical wear component in the water pump cooling system of 35-60 HP Johnson and Evinrude 2-stroke outboards. The plate is typically included in complete water pump kits (part 0384087/384087) alongside impeller, housing, wear plate gasket, grommet, seal, O-ring, wedge keys, bolts, and washers. This component wears over time with saltwater operation and should be replaced during routine water pump service. Proper installation with new gaskets ensures effective cooling circulation and prevents engine overheating in marine service.
